To solve this problem, all you have to do is set up a proportion, letting x represent Kenneth's average speed per hour.
184.25/3.35 = x/1
Now, we use cross products, or the multiplication of the numerator of one fraction times the denominator of another fraction, and setting them equal to one another.
3.35x=184.25
Finally, we divide both sides by 3.35, because it's the coefficient of x, and we are trying to get the variable x alone.
x=55
Therefore, Kenneth's average speed was 55 miles per hour.
